Description

PROCEDURE FOR FORMING A CYLINDER CLEANING BRUSH FORMED CLEANING BRUSHES IN ACCORDANCE WITH THE PROCEDURE The present invention relates to a procedure for forming a cylinder cleaning brush, in particular for working cylinders, for use in hot rolled strip mills, especially in hot rolled strip mills, having a brush coating comprising a carrier base supported on the end with a brush coating attached thereto, which is pressed against the cylinder with an adjustable force or a determined immersion depth to achieve a cleaning effect, a cleaning brush manufactured in accordance with the procedure as well as a cleaning brush operation process.
In hot strip aluminum rolling mills, it is necessary to clean at least the working cylinders during the rolling process. To this end, rotating brushes are pressed against the working cylinders to keep the cylinders free of emulsion residues, oxide particles and material to be laminated, etc.
Cleaning of these working rollers is essential to ensure a smooth and satisfactory surface quality for the laminated strip. The type of brush often used is the wire brush. Coatings of this type of brush have a relatively high stiffness and therefore they can only fit extremely imperfectly to the contours of the cylinders. The wire brush consists of a carrier base body and a brush coating attached thereto, the so-called trim. The latter consists of brush hairs made of corrugated steel wire. To achieve the cleaning effect, the brush is pressed against the cylinder with a determined force or with a defined dip depth for the steel wires. In this context, of course, the brush is flexed. When a cylinder-shaped working cylinder and a cylindrical brush shape are used, a biasing force occurs which, as a function of brush flexion, is greater in the edge regions and lower in the center.
However, when special forms of grinding are applied to the working cylinders, then when tightening the brush against them a gap must first be overcome between the working cylinder and the wire brush before a contact can be made between the brush and the total length of the working cylinder. The pressure force exerted in this context, however, is necessarily uneven. In regions where a higher pressure force is exerted, increased brush hair wear may occur. In regions where a lower pressure force is exerted, on the other hand, a locally reduced cleaning effect and even non-contact should be expected. However, the operating conditions on the cylinder table length and application duration are uneven, which is disadvantageous for the rolling of many aluminum alloys and other non-ferrous metals, due to the surface quality. This is because, as the adjustment range of contoured cylinders increases and the diameter difference by the table length of the working cylinders increases correspondingly, the problem, namely the irregularity, increases substantially.
One of the fundamental purposes of hot and cold strip lamination is to produce a profile with good strip smoothness and fully meeting the requirements of the laminated product. Even the strip profile is influenced by numerous factors such as thermal bulging, cylinder wear and rolling forces. For this reason there is a need to adjust the bulging of the working cylinders currently. To this end, a continuously modifiable cylinder with a continuously modifying (Continuously Variable) has proved to be the most suitable adjustment mechanism. In this context, especially the working cylinders are ground in the approximate shape of an S. Both working cylinders have identical grinding: The grinding of the upper cylinder is offset by 180 ° from the lower cylinder so that they complement each other and resulting in a symmetrical contour of the space between the cylinders. EP 0 605 833 BI has disclosed to the public a device for adjusting a brush cylinder, especially next to a working cylinder of an amount of hot-rolling aluminum cylinders, the brush cylinder can be turned in the opposite direction. rotation of the working cylinder and is supported on both sides by rotatable clamping devices, and is positioned parallel to the working cylinder so that it can be moved in translation. The pivoting bearing of each brush roller fixing device is positioned close to the working cylinder hardware. The clamping device has a pivoting lever which is between an adjustable drive member and a repositionable support member, the drive member being positioned in the balance block or optionally in the folding block for the cylinders. workers, and the support member is positioned near the hardware of the worker cylinders. EP 0 394 873 B1 describes a procedure for laminating a cold aluminum strip in a laminating device having at least one pair of working rollers and one pair of bearing rollers, each bearing roller being positioned in such a manner. to be in contact with a working cylinder. A cleaning brush is provided for each support cylinder, which is arranged at the open end of a channel mechanism to touch the support cylinder and brush it. The procedure is determined by the following steps: • Rotation of the brush in a direction opposite to the support cylinder; • Air suction through the open end of the channel mechanism, the air intake speed being at least 5 m / sec and the channel mechanism is provided with tilting parts and a mechanism to be pushed forward and pulled back; • Adjustment of the positions of the tilting parts to keep the open end of the channel mechanism at a predetermined distance from the support cylinder. EP 0 640 412 A1 describes a roller cleaning and polishing device which comprises a rotatable cleaning cylinder arranged on a support member having two parallel arms extending between an inner end and a outer end and which are supported parallel to the axis of the cylinders respectively on two aligned fixed bearings, the rotating cylinder being driven by a kinematic chain which can be rotated about the gear axis. JP 9057313 A relates to the problem of destroying the surfaces of a plate to be laminated and the problem of debris sticking during the rolling of aluminum plates. To address these problems, the document proposes to position brush rollers close to the working rollers on an amount of cold rolling rollers, so that when in contact with the working rollers they can remove the layer that has stuck to the surface of the rollers. Worker cylinders. JP 10034210 A relates to the task of preventing slag particles from sticking to working cylinders. To solve this task, the document proposes to position a brush roller to clean each worker roller. To this end, the brush cylinder has a hollow body through which a coolant can be conducted, with outlet holes arranged radially in the hollow body. US-A 2,953,952 discloses a cleaning brush for cleaning the cylinders of an amount of cylinders. The cylinders are cylindrical and the outer contour of the cleaning brush is cylindrical in shape. When the cleaning brush is pressed against the cylinders, an uneven load arises which results in uneven wear. JP 52 09 28 55 has brought to the public's knowledge a cleaning brush that can be fitted to a cylindrical working cylinder of an upstream cylinder having four cylinders, and which is reached with pressure or tensile forces at its ends. support.
This results in a convex or possibly concave force tracing over the length of the cleaning brush. It is also proposed to adopt a cleaning brush with a parabola-shaped brush coating. However, it is not possible to prevent the brush coating from becoming unevenly worn.
Based on the state of the art as described above, the present invention has as its fundamental task to configure or optionally create a cleaning brush such that a homogeneous pressure force is established between, for example, a working cylinder and the cleaning brush the entire length of the cylinder table, even when the working cylinder has a table shape of any contour.
To solve the task, the present invention envisages adopting a procedure for shaping a cleaning brush, in particular for working cylinders, for use in metal strip hot rolling trains, especially in hot rolling mills. aluminum strips according to the generic term of claim 1. The present invention provides that the shape of the brush liner, i.e. the cleaning brush, is configured according to the geometry of the cylinder with a contour conforming to with the mathematical functions of a polynomial, with an exponential function, with an angular function or the like, and having a minimum pressure force sufficient to produce a cleaning effect.
In this context, another embodiment of the present invention provides that the shape, i.e. the contour of the brush coating or the cleaning brush, is suitable for the geometry of the cylinder, in particular the working cylinder, and is configured with a contour. in accordance with the mathematical function of any polynomial, with an exponential function, with an angular function or the like. And finally, the cleaning brush according to the present invention is configured in such a way that it is provided with means to be moved in the direction of its axis, at least in one of the end supports or, eventually, to be coupled. with the movable worker cylinders.
With regard to the operation of the cleaning brush, the present invention provides that the shape of the brush coating, i.e. the shape of the cleaning brush, is adjusted to the shape of the cylinder to such an extent that it is exerted between the cylinder and the brush coating, i.e. the cleaning brush, a considerably homogeneous pressure force over the length of the cylinder table, preferably having in the region of the cylinder corresponding to the width of the strip a minimum pressure force F & sufficient to obtain the cleaning effect (figure 4a).
In addition, the operating procedure is characterized by the fact that the bending of the brush base body as well as the thermal bowing of the cylinder, which occur in practice, are offset by a corresponding symmetrical bending of the brush coating, taking into account the influence of the stiffness of the brush base body. And finally, the procedure according to the present invention provides that if the working cylinder undergoes axial displacement during operation to a certain extent conditioned by the function, the cleaning brush will also be displaced, preferably by a equal and in the same direction so that it can maintain its longitudinal position and its cylinder shape relative to the cylinder. In the case of fixed brushes, the pressure force would have to be adjusted.
Other embodiments of the cleaning brush in accordance with the present invention are set forth in the subclaims.
Details, features and advantages of the present invention may be inferred from the following explanation of an exemplary embodiment shown schematically in the drawings.
They show: Figure 1 A front view of two cylindrical working cylinders acting in conjunction with cylindrical cleaning brushes;
Figure 2 The flexing of a cylindrical cleaning brush when used to act in conjunction with a cylindrical working cylinder;
Figure 2a A diagram of the pressure force of the cleaning brush in accordance with the illustration of Figure 2;
Figure 3 The different intensity of a pressure force between a working cylinder and a cleaning brush when using a working cylinder configured with an S-shaped contour interacting with a cylindrical brush;
Figure 3a The region of greatest brush wear in accordance with the illustration of Figure 3; and Figure 4 A working cylinder and a cleaning brush if both the working cylinder and the cleaning brush are configured with an S-shaped contour.
Figure 4a Diagram of operating pressure configuration in accordance with the illustration of Figure 4. The illustration of Figure 1 shows a pair of working rollers 4, 4 'during the rolling of a laminated strip 8 in the space between the rollers. The surface regions of the working cylinders 4, 4 'exiting the space between the cylinders 8 are captured by cleaning brushes 1, 1 which rotate in the opposite direction and are cleaned of dirt such as emulsion residues, laminated material which adhered to them well. as oxide particles. The representation shows the front sides of the working cylinders 4, 4 'as well as the cleaning brushes 1,1a. Working cylinders and cleaning cylinders are configured in cylindrical shape. The illustration of figure 2 shows a side view of the worker cylinder 4 interacting with the cylinder-shaped cleaning brush 1. The cleaning brush is pressed on both sides against the working cylinder 4 with a pressing force Fb / 2, and in this context forms a bending D. As shown in Figure 2 also shows, the cleaning brush comprises a body base 3, preferably steel, with a brush coating 2. The latter consists of corrugated steel wires. The illustration of Figure 2a shows a bending diagram as a function of the varying pressure force between the working cylinder 4 and the cleaning brush 1, including comparatively between a soft brush 1 'and a hard brush, in particular a cleaning brush. 1 '' steel wires. The diagram of the illustration of Fig. 3a shows the region of highest pressure force as well as the contiguous region 7 of lower pressure force and, consequently, of less cleaning effect, when a combination of a working cylinder 4 configured with a S-shaped contour and a cylinder-shaped cleaning brush 1 according to the illustration in figure 3.
In the opposite direction, the diagram shown in the illustration of figure 4a shows a homogeneous pressure force over the length of the cleaning brush 1.
Such an optimum thrust force is achieved by adopting, in accordance with the present invention, a working cylinder 4 configured with an S-shaped contour interacting with a cleaning brush 1 having an S-shaped contour.
In this context, the grinding shape of the brush 5, 5 'is adjusted so extensively to the shape of the working cylinder 4 that a minimum pressing force FB can be chosen to obtain a sufficient cleaning effect.
In this context, the shape of the brush coating 2 may optionally be configured with parabolic grinding, grinding of any polynomial, exponential function, angular function and the like according to the working cylinder geometry 4.
It has been found to be quite advantageous in this context that the flexing D of the brush base body 3 as well as the thermally bending of the working cylinder 4, which are in practice, are compensated by a corresponding symmetrical bending of the brush coating 2, leading to consider the influence of the stiffness of the brush base body 3.
In case the working cylinder 4 is axially displaced during operation to a certain extent conditioned by the function, the cleaning brush will also be displaced, preferably to an equal extent and in the same direction, so that it can maintain its longitudinal position in relation to the working cylinder as well as its cylinder shape, and / or the brush pressure force will be modified. The cleaning brush for use with metal hot rolling trains, and particularly on aluminum hot rolling trains, is provided with a brush coating 2 formed of corrugated steel wires.
To the extent that the contour of the cleaning brush fits from the beginning of the contour of the working cylinders and that this adjustment applies to any axial displacement position of the working cylinder, a substantially homogeneous pressure force is always guaranteed and thus a optimal cleaning of the working cylinders.
